Re: Valve marks on head

Clay / putty test is a good way to check the clearance. Looking closer at the head the circular area appears to be more visible closer to the center of the combustion chamber.
Since the chamber is higher in the center I would think any contact with a valve should be seen closer to the edge of the chamber.
I've also place a head on the block without a gasket and no head bolts. Slowly turned the engine over by hand, looking for movement of the head.
Or just borrow the kids Play-dough and place some on top of a valve.
